Ionic bonding Flashcards
What is an ion?
An ion is a charged atom.
How are ionic compounds formed?
Ionic compounds are formed by the transfer of electrons when metal elements react with non-metal elements.
What is an ionic bond?
An ionic bond is the electrostatic attraction between oppositely charged ions.
Do ionic compounds have high melting and boiling points?
Ionic compounds have high boiling and melting points.
Do ionic compounds conduct?
Ionic compounds do not conduct in the solid state but do conduct when molten or in solution.
Do metal atoms gain or lose electrons?
Metal atoms LOSE electrons to form POSITIVE ions.
Do non-metal atoms gain or lose electrons?
non-metal atoms GAIN electrons to form NEGATIVE ions.
How do you find out if an ionic compound is soluble in water?
To find out if an ionic compound is soluble in water, check the solubility table in the data booklet, page 8.
Are ionic compounds soluble in water?
Many ionic compounds are soluble in water.
What happens when ionic compounds dissolve?
As they dissolve, the lattice structure breaks up allowing water molecules to surround the separated ions. The ions are now free to move.
Do ionic compounds conduct in a solid state?
Ionic compounds do not conduct in the solid-state because the ions are not free to move, as they are held rigidly in the crystal lattice by strong ionic bonds.
Do ionic compounds conduct when in molten or in solution?
Ionic compounds conduct when molten or in solution because the ions are free to move. Melting and dissolving breaks up the crystal lattice.
What is the process electrolysis?
During the conduction of an ionic solution or molten ionic compound, the ions move towards the oppositely charged electrodes. Positive ions move towards the negative electrode and negative ions move towards the positive electrode.
